Detailed Description

The VFS_nopasswd authenticator uses a nopasswd file to store username, uidnumber, a real name, and group membership.

The format of the nopasswd file is:

username1 uidnumber "Real Name" group1,group2
username2 uidnumber "Real Name 2" group2,group3,group4

Each line is separated by a newline and contains usernames who are allowed password-less authentication.

If the uidnumber is not present or does not parse as an integer, it will default to 0.

The real name field should be surrounded by quotes and is optional. If the real name is missing the username will be used.

The group field is a comma separated list and is optional. If missing, the user will not belong to any groups.

Spaces should only appear between fields or within quotes for the real name.

Parameters

nopasswordFile Path to the nopasswd file

Auth requests will check for the existence of a username to determine authentication.

Member Function Documentation

◆ ls()

void VFS_nopasswd::ls ( VFS_request * r )

protectedvirtual

List the users available for this auth method.

Parameters

r	The VFS_request object

Reimplemented from VFS_node.

Definition at line 109 of file VFS_nopasswd.cpp.

◆ read()

void VFS_nopasswd::read ( VFS_request * r )

protectedvirtual

Perform an authentication request by read()ing from this node.

Parameters

r	The VFS_request object

When a user requests authentication against this node, the nopasswd file is opened and each line is sequentially read and tested against provided credentials.

Credentials must be supplied in the VFS_request::_data object:

d["username"] = "username";

If no matching lines are found, r->_success = false will be set.

Reimplemented from VFS_node.

Definition at line 59 of file VFS_nopasswd.cpp.

◆ reportDetails()

QString VFS_nopasswd::reportDetails ( )

virtual

Additional details for a generated report.

Returns: A string containing the additional details.

This is useful in subclasses for providing class-specific information of any kind. For instance, VFS_cron::reportDetails() will list all active events.
